Clearance of microfilariae from the circulation of hamsters infected with Dipetalonema viteae was demonstrated following passive transfer of serum obtained from hyperinfected hamsters. The exclusion fraction after gel filtration of this serum on Sephacryl S 200 also cleared microfilariae whereas the other fractions did not. There was no clearance with serum taken during the pre-patent, patent o...

In five healthy mongrel female cats used, four cats (Cats 1-4) were experimentally inoculated with 100-123 larvae (L(3)) of Dirofilaria immitis. Cat 5 was an uninfected control. Only Cat 1 became microfilaremic on Day 201 after inoculation and the diurnal changes in the microfilaria population were monitored every 2 h for 24 h on Day 237 when a sufficient number of microfilaria were detected in...

It has been reported (1, 2) that intraperitoneal implantation with two male and two female adult Setaria cervi produces microfilaremia in rats within two weeks and lasts from 54±6 days. When the number of worms implanted is increased, microfilaria appear earlier but the mortality of the host is higher. Complete disappearance of microfilaria from peripheral circulation results after oral and int...

PURPOSE To evaluate eye manifestations in mansonelliasis patients from Coari, AM, rural area on the middle Amazonas River. METHODS Cross-sectional study consisted of evaluation of 543 subjects from Coari rural area on Solimões River right margin. All subjects were submitted to blood test for microfilaria and the subjects who had a positive test also were submitted to skin biopsies and ophthal...

Microfilaria infection is one of the major health problem in developing countries like India, especially in rural areas. In most of the cases microfilaria was an incidental finding in FNAC smears prepared from swellings from various locations in the body and also from fluid aspirate. Peripheral blood smear examination is usually done for the diagnosis. Here, we presented a series of eight cases...

subtropics and is endemic in India1. In India, Wuchereria bancrofti accounts for 90% of the total filarial infections2. The disease can present as silent clinical disease or as lymphadenitis, lymphangitis or elephantiasis1. The diagnosis is conventionally based on demonstration of microfilaria in the peripheral blood smear. There are very few case reports describing microfilariae in bone marrow...

Filariasis is a common disabling parasitic disease in this region and cytological diagnosis is often not required. Cytology has important role in diagnosis of sub-clinical filariasis. Most cases of cytologically diagnosed filariasis are clinically unanticipated. Microfilaria, ova and fragments of adult worm of Wuchereria bancrofti, in exfoliative as well as aspiration cytology have been reporte...

INTRODUCTION Filariasis is an endemic disease with worldwide distribution in tropical and subtropical regions. It is uncommon in Qatar. The conventional diagnostic procedure is the demonstration of microfilaria in blood smears. Even with its high incidence, it is unusual to detect microfilaria in fine needle aspiration cytology (FNAC) smears. Although the 'filarial dance sign' is rarely documen...

This study examined circulating filarial antigen by monoclonal antibody Og4C3-enzyme-linked immunosorbent assay (ELISA) from 114 men with hydrocele, living in an endemic area. Nocturnal blood and hydrocele fluid were collected and examined for microfilaria. ELISA was performed on serum and hydrocele fluid for detection of antigen. Amongst 114 cases, 5(4.4%) showed microfilaria in blood but none...
